In my opinion, none of your children wll be potty trained until they want it as much as you. So, your job isn't to get them to use the potty but to want to use the potty, cuz trust me, both know how to use it. They just don't know why they should. I had tried rewards, praise, charts, etc... with first & it just seem to become a power issue more than anything else. One day, I just had a revelation and I told my daughter what I wanted & expected. she was 2 3/4 yrs old. I then told her that it was her choice whether to use or not, but her choice had consequences. I explained that I was tired of cleaning nasty poo poo & that if she chose to poo in her panties, then she would help clean them & she would help clean the mess. So I would strip her down from the waist & put her in the tub & I woul;d have her help clean her nasty panties. She did not like this, nor did she like the cold water that I used to clean her & I would have her help clean as well. I explained that warm water was for bathtime only. Obviously I was trying to make the ordeal of pooing in her pants very uncomfortable. Cold water does not hurt anyone. I never got angry nor did I act smug, just matter of fact. I explained that as a person grows, their poo gets bigger & messier & that is why big kids & grown ups use the potty. When my daughter would ask for non necessity for life things, such as chocolate milk, I would answer with one question, "did you poo poo on the potty today?" she would say "no" and I would tell her that she already had her answer then. She got it! It took 4 days of her testing me to see if I would stick with it, but I will never forget the day she yelled, "i did it, I did it" Mom come look" I went in & there she was, just beaming. I was thrilled & I helped her wipe & she looked right at me and asked Can I have some chocolate milk now? I asked did you poo poo on the potty? she screamed with delight "yes" & she EARNED herself a nice big cold glass of chocolate milk! That was it for her. She got it & we never looked back. My son really just followed suit since his sister did it he really didn't fight it & when I told him he was big enough etc.. consequences etc.. he tested it once then easily went with the flow. both of mine were trained 2-3 months prior to their 3rd birthday. Now night time was harder & with first I used pull ups etc... I didn't want to rush her etc.. but honestly, I got tired of the pull ups & tired of doing laundry with all the sheets. she slept so hard she'd just sleep in the pee. disgusting! So I decided to have them go at 8pm (bedtime) then I would wake them both & have them go at 10pm right before i went to bed, then I set my watch alarm for 1am & I'd wake them again then they would make it till 6am at which time I'd wake them again. After about 2 months, they started begging me not to wake them that they would do it themselves. I cut out only the 1am time & tested them & sure enough, they did it! we've rarely had any accidents & they go on their own & don't disturb anybody else & go back to bed on their own. It is great! daughter was about 4 & son was 3. they are both now 4 & 5 & I can't remember the last accident. Hope this helps you. Best of luck.
